Review of Thermally Activated Twisted Coiled Polymer Actuators: A Materials Science Perspective

open access: yesAdvanced Functional Materials, EarlyView.
Thermally activated twisted and coiled polymer actuators (TCPAs) combine lightweight design, large deformation, and scalable fabrication for soft robotic and wearable applications. This review connects polymer structure, processing history, helix geometry, and thermomechanical characterization to actuator performance, highlighting current challenges in

The role of mental toughness and affect in academic success within a higher education setting

open access: yes
‘Mental Toughness’ is recognised as an important component in academic success (Robinson 2013) represented by the psychological qualities that determine how challenges are effectively addressed in pressurised situations (Dewhurst et al. 2012).

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

open access: yesAdvanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including
